2 Claims.

This invention relates to a novel construction of ventilator anddeflector for use with storm sashes and to provide means for permittingsufficient air through a storm sash to afiord adequate ventilation andwithout opening the sash or removing it from its normal position withinthe window frame.

More particularly, it is an object of the invention to provide aventilator and deflector capable of being readily applied toconventional storm sashes and which is of extremely simple constructioninvolving a minimum of moving parts which may be applied to and used inconjunction with a storm sash with only a slight modification of thestorm sash.

vStill another object of the invention is to provide a device of theaforedescribed character which will efiectively deflect the air enteringthrough the storm sash for eliminating a direct draft from the air whenit is admitted through the conventional window sash and into a room orother enclosure.

Various other objects and advantages of the invention will hereinafterbecome more fully apparent from the following description of thedrawings, illustrating a preferred embodiment thereof, and wherein:

Figure 1 is an elevational view, partly in vertical section lookingtoward a portion of the lower part of a storm sash and showing theventilator and deflector mounted on the inner side thereof;

7 Figure 2 is a horizontal sectional View taken substantially along aplane as indicated by the line 2-2 of Figure 1;

Figure 3 is a vertical sectional view taken sub-, stantially along aplane as indicated by the line 3-3 of Figure 1;

Figure 4 is a view similar to Figure 3 but showing the ventilator in anopen position and the draft deflector in an operative position;

Figure 5 is a vertical sectional view taken substantially along a planeas indicated by the line 55 of Figure 4;

Figure 6 is a plan view of one end of the deflector and closure; and

Figure '7 is an enlarged horizontal sectional view taken substantiallyalong a plane as indicated by the line 1'| of Figure 3.

' Referring more specifically to the drawings, the ventilator anddeflector in its entirety is designated generally 8 and for the purposeof illustrating the application and use thereof, the numeral 9designates a portion of a window sill forming a part of a window frame,not shown, containing sliding sashes, a portion of the lower 2 sash 10of which is illustrated in Figures 3 and 4. A storm window, a portion ofwhich is illustrated and designated generally I2 is adapted to bemounted'in any suitable manner in the window frame of which the sill 9forms a part and has a bottom rail or bar [3 which rests upon the sill9. As clearly illustrated in Figures 3 and 4, the storm window I2 isspaced outwardly a considerable distance from the lower sash ID as isconventional in the mounting of storm windows and the ventilator anddeflector 8 is adapted to be disposed in said space and secured to theinner side of the.

lower, rail or bar [3 and when thus disposed is spaced a considerabledistance outwardly with respect to the sash l0. I The ventilator anddeflector 8 includes a housing, designated generally [4 comprising anouter wall [5 which is disposed substantially parallel to the rail l3and provided with inturned portions at the endsthereof forming sidewalls l6 which extend towardthe rail l 3 and which terminate inQut-turnedflanges, llwhich abut against the inner side of the rail- [3and are secured thereto by suitable driven fastenings IS. The outer wall[5 is provided with an inturnedlip or flange l9 at its bottom edge whichis disposed in substantially the same plane as the bottom edges of theside walls It. As best seen in Figures 3 and 4, the upper surface of thesill 9 on which the storm sash rail l3 rests slopes outwardly anddownwardly and the housing I4 is secured to said rail so that therounded corner formed by the juncture of the wall l5 and the lip I9 willrest on the upper surface of the sash 9 and will form the only portionof the housing [4 in engagement therewith.

The only modification of the storm sash which is required for use of theventilator and deflector 8 is the provision of one or a plurality ofopenings 29 therein and which are located between the walls I6 in thebottom rail I3; three openings being shown in Figure 2, although it willbe readily apparent that agreater or less number of openings could beproyided or, if desired, a single elongated opening could be employed.

Each of the side walls I6 is provided with two longitudinally spacedrollers 2| and 22 which are disposed in substantially the same plane andwhich'are journaled on pins or rivets 23 which are anchored in said sidewalls l6. As best illusopening outwardly of its shank end for receivinga threaded stem 28 which is removably mounted therein and provided witha head 29 at the outer end thereof for retaining the roller 2| or 22 inrotatable engagement with the stem 24.

The rollers 2| are disposed in longitudinal alignment and adjacent theinner side of the rail l3 and the rollers 22 are similarly aligned anddisposed adjacent the wall l5 and spaced approximately the same distancetherefrom as the rollers 2| are spaced from said rail l3. A combinationvalve and deflector plate 30 has a lower portion which is adapted to beinserted between the rollers 2| and the inner side of. the rail |3 orbetween the rollers 22 and the inner side of the wall l5. When in thefirst mentioned position, said lower portion of the plate, 30 will bedisposed between the rollers 2| and the inner side of the rail l3 andretained by said rollers 2| in tight engagement with the rail |3 so thatthe ventopenings of the'rail will be effectively closed and sealed bythe lower portion 3| of the plate which thus forms a valve or closure.The upper portion 32 of the plate 30 overlies the ends of the lowerportion 3| to provide the downwardly facing shoulders 33 which rest uponthe uppe edges of the wall Hz for supporting the bottom edge of theplate out of engagement with the sill 9. The plate portion 32 terminatesat itsupper edge in an arcuate portion 34 which is disposed to curveinwardly and away from the storm sash l2 when the'plate 30 is in itsaforedescribedposition as illustrated in'Figure 3. To position the plate30 to function as a deflector, said plate is drawn upwardly and therebydisengaged from the rollers 2|, rotated a half turn and inserted betweenthe rollers 22 and the wall Hi and with the lowerportion 3l-thereofdisposed in the housing M, as in its previously described position. Withthe closure portion 3| disposed against the inner side of the wall l5,as illustrated in-Figure 4, it will be readily apparent that saidclosureportion will be spaced from the openings 20 so that air maypassfreely through said openings and the air will be deflected upwardlybythe plate 30 and back toward the storm sash f2, above thebottom rail|3'by' the flared upper edge 34; which is disposedto extend toward thestorm sash, due to the rotation of the plate 30. It will thus bereadilyapparentthat the air entering the openings 20 will substantiallyfollow the path as indicated by the'arrows in Figure 4 and accordinglywillenter the opening formed between the sill 9 and the raised lowersash I0 without creating a draft.

The rollers 22 are preferably formed of rubber or other relativelyresilient material for yieldably retaining the plate 30 in its positionof Figure 3 against the storm sash bar |3 for effectively closing thevent openings'20.

Various modifications and changes are contemplated and may obviouslyberesorted to, without departing from the spirit or scope of theinvention as hereinafte defined by the appended claims.

We claim as our invention:

In combination with a window sash having a bottom rail provided withat least one vent opening, a housing secured to the inner side of saidsash rail and with which said vent opening communicates at its innerend, said housing having an inner side wall spaced from said sash railand an open top, a combination closure and defiector plate insertablethrough said open top of the housing, a first means connected to anddisposed in said housing adjacent the sash rail to engage and press aportion of the plate against the inner side of the sash rail for closingsaid vent opening, a second means connected to and disposed in saidhousing adjacent said inner side wall to engage and hold said plateportion against the inner side wall and out of engagement with the sashrail for admitting air to the housing through the vent opening, and saidplate having a deflector portion extending upwardly from the housing andcurved toward the sash, when the plate is disposed against said innerside wall, for deflecting the air rising from the housing back towardthe window sash, said housing having end walls disposed substantiallyperpendicular to said sash rail and inner side wall, said first meansand second means each comprising a pair of rollers journaled in thehousing on said end walls.
